JAR FOR SUBMARINE AND LIKE BATTERIES.

Specification of Letters Patent. 1

Application filed April 2, 1917. Serial No. 159,130.

To all whom it may concern:

Be it known that I, BRUCE FORD, a citizen of the United States, and a resident of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have. invented a certain new and useful Jar for Submarine and like Batteries, of which the following is a specification.

The principal objects of the present invent1on are, first, to provide battery jars and thelr underlying supports or pedestal arrangements which constitute and can be moved and installed as unitary structures, and which are self-seating in respect to irregularities in the floor upon which they rest; and second, to protect the floor upon which a battery of jars rests from injury by the wedges which are usually driven in between the individual jars or between the ars and the walls of the battery tank or compartment.

The invention will be claimed at the end hereof, but will be first described in connection with the embodiment of it chosen features of the invention.

A special feature of the invention is that the edestal-supports 1 are made art of the ar and they afford insulation etween the jar bottom and the floor of the lead lined steel tank or compartment inwhich the battery is usually installed. This floor usually consists of plates of steel 2, on top of which is generally arranged a leveling packing of wood, tar paper or felt 3, and on top of this tar paper or felt is a lead lining 4. In the lead lining 4 there are seams of which one is illustrated at 5. These seams are one .source of irre larity in the surface of the floor upon which the jars are supported. In

respect to such irregularities in the surface of the floor a jar embodying features of the invention is self-seating. The foot 6 of the pedestal-support is dlgitated as at 7 and consists of a soft or semi-soft rubber insert arranged in the pedestal 1, which latter is preferably a part and parcel of the material of the jar bottom and is provided with a depending petticoat flange 8 for diverting drip. The bases 9 of the wedging ribs 10 of the jar are extended beyond the ribs to provide wedge-stops 11. Referring to Fig. 4, a

wedge a, is shown in line with and above a wedge stop 11, past which its lower end may not be driven.

In use the jars and pedestal 1 and their feet 6 constitute a unitary structure so that the jars can be readily placed in or moved to any desired position in the battery room. The fingers 7 acting as cushions. absorb any irregularities in the surface of the fioor and this is illustrated at 5 in Fig. 3. When the wedges a, grooved to slide on the wedging rib 10, are driven in between the individual cells, as is frequently done in submarine and like batteries, the wedges are stopped by the wedge-stops 11 and so may not be driven into contact with the lead of the floor, which they might readily injure, and the wedges, being of wood, if in contact with the floor or with acid thereon would be rotted or might cause short circuits.

It will be obvious that modifications may be made in details of construction and ar-' rangement and that certain of the described features of the invention may be used with out the others, so that the invention is not limited as to those matters or otherwise than as the prior state of the art and the appended claims may require.

What I claim is:

1. A jar for submarine and like batteries having integral therewith pedestal-supports each provided with a petticoat drip flange and with. a digitated cushion foot connected thereto, the jar and support and foot con-' stituting a unitary structure that can be moved as such.

2. A jar for submarine'and like batteries having mtegral therewith pedestal-supports each provided with a pettlcoat drip flange and with a cushion foot connected thereto, the jar and support and float constituting a unitary structure that can be moved as such.

3. A jar for submarine and like batteries having integral therewith pedestal-supports Patented July e, 1918.

each provided with an attached cushion foot and a petticoat drip flange surrounding the cushion foot, the jar and support and foot constituting a unitary structure that can be moved as such.

4. A jar for submarine and like batteries having integral therewith pedestal supports each provided with a digitated cushion foot attached thereto, the jar and support and foot constituting a unitary structure that 1 0 can be moved as such.

5. A jar for submarine and like batteries having the base of its wedging ribs extending beyond the ribs to provide wedge-stops.

6. A jar for submarine and like batteries 15 provided with wedge stops.

BRUCE FOR-D.
